Having successfully pulled off the biggest show of his career (this year's Superbowl half-time show) Bruno Mars is flying high. His last record Unorthodox Jukebox, an eclectic melting pot of Motown, hip-hop and pop influences, solidified his status as one the world's most successful solo artists. The live arena gives him a chance to display his startling virtuosity, equally at home behind the piano or showing off some James Brown-esque shimmies centre stage. He'll be supported on these North American tour dates by Aloe Blacc, who rose to fame with his track I Need a Dollar.
